I have all the Radiohead albums (love them) for a beginner of Radiohead go with Sicy and start with THE BENDS... I don't know it just seems like it's the easiest to digest, good clencher. Then move on to Pablo Honey, OK Computer, Amnesiac, Kid A (in that order)...

I say definitely start out with The Bends, because OK Computer will be a little too weird to start out with. The Bends will be easier to digest, and has more radio-friendly songs on it. OK Computer will take you to the next level.
